Grey horizontal lines during playback on camcorder

I have recently acquired an older model camcorder, a Canon MV630i and I find that whatever i record when i play it back there are horizontal grey lines across the whole screen. I think it might be the tape as the one i am using is an old one from when someone else had the camera.

This is usually caused by a defective CCD image sensor and can be repaired fairly inexpensively. However, it's not a user serviceable problem and will need to be repaired qualified service technician.

Horizontal grey lines on tape playback


please state the age of your devices. It can help a great lot in solving your problems. The lines that you get aren't continuous, are they? They appear to be going up and down, are different sizes and shift as the tape plays, yes? well, this is simple. You need to clean your recording head.

Horizontal grey bars across screen.


Hi,
This sounds like it is the Tape recording function that is at fault. Unfortunately, it's also one of the most difficult to correct without a scope and test jig.
However,
If it is more than 5 years old, it may be suffering from component failure.
In particular the Electrolytic capacitors in these small cams seem to fail first due to temperature and humidity changes. They can leak, dry up or corrode, so it may be worth looking inside at the control boards to spot any physical signs of deterioration.
This shows typical surface mount capacitors - silver cylinders with black segment denoting negative -

Canon XL2 wont record or playback tapes - grey


Sorry to hear your situation, usually when serviced by a technician, head and tape path is cleaned and adjusted. During use you will encounter pixelation problems occur and most case tape cleaner should resolve the problem. Your condition is where if all the system is ok and have a heavy clogging on the heads, requires technician to clean each head manually to bring it back. so look for a camcorder repair facility locally and get cleaned. If you cannot find one, the service is provided for around $100 at www.camerarepairjapan. Good Luck

Grey Bars appear on video playback


The monitor you view while recording does not read from the tape where the problem is located, that's why you are not seeing them during recording.
Since they are not visible while recording, the video section is healthy, only the recording is faulty and it is unlikely you can do anything at home to correct it.
This may be a common problem and perhaps Canon is familiar with it.
I recommend you call their service line directly:

Horizontal lines on playback screen


Someone here recommended on another post to put the lense cap on & videotape the blackness in a quiet room for 5-10 mins. I tried this as a last resort & it worked. When I played back the tape, no more skipping or gray lines. I had 4-5 SOLID gray lines with skipping video & audio in between on every tape I put in. I think the person who helped me solve this said that it was a result of the tape alignment going off. My camera is a Canon zr80 digital camcorder. (Called Canon, they had me reset it & then recommended sending it in).

Hey,

I just started to have the same problem, 5 grey lines and intermittent audio. I the settings and i tried different tapes and No Joy. Then I tried to record onto an old tapes to see if the new recording would do it and the camera showed me a strange icon for exposure. I set the exposure back to 'Easy' and Viola, I recorded and the playback is now clean. Even old tapes play OK now...

The settings must have gotten wacked somehow. I glad it worked out, good luck.
